腰是“一身之要”,结构复杂,由5个腰椎骨以关节相连,上连胸椎,下接骶骨,并由丰厚的肌肉和坚强的韧带、筋膜加强。身体绝大部分重量经腰部向下传递,活动度也相当大。随着年龄的增长,人的肾气亏损,骨骼中矿物质成分增多,骨质发生纤维性变化或钙化,关节和韧带弹性减弱,关节活动度相对变小,肌肉也逐渐萎缩,肌肉的力量和弹性都降低,加上应变能力减 Waist is “a must”, complex structure, by the five lumbar spine to the joints, even the thoracic spine, the next sacrum, and by the rich muscle and strong ligaments, fascia to strengthen. Most of the weight of the body through the waist down, the activity is quite large. With age, loss of kidney gas, increased mineral composition in the bones, fibrosis or calcification of the bone, weakened elasticity of the joints and ligaments, relative decrease in joint mobility, gradual muscle weakening, muscle strength and Elasticity is reduced, coupled with the ability to reduce strain
